Film Tear is a form of degradation in archived film and is the physical ripping of the film material. Tear causes displacement of a region of the degraded frame and the loss of image data along the boundary of tear. In ...

This paper describes initial work on a framework for automatic detection of illegal dumping from CCTV footage from recycle centres. Frames are seperated into foreground and background regions using a Bayesian approach that ...

Speech models and features that emphasise the dynamic aspects of speech can provide improved speech recognition. The cepstral time matrix has been established as a successful method of encoding dynamics. The paper extends ...

An auditory nerve model allows faster investigation of new signal
processing algorithms for hearing aids. This paper presents
a study of the degradation of auditory nerve (AN) responses at
a phonetic level for a range ...

Hearing loss research has traditionally been based on perceptual criteria,
speech intelligibility and threshold levels. The development
of computational models of the auditory-periphery has allowed experimentation
via ...

This paper investigates the use of voicing information as an
additional cue in contrast enhanced frequency shaping (CEFS)
of speech to improve perception in the hearing impaired. The
presented work builds on an existing ...

In Psychology it is common to conduct studies involving the observation of humans
undertaking some task. The sessions are typically recorded on video and used for subjective
visual analysis. The subjective analysis is ...

A computational model of the auditory periphery enables faster investigation
of new signal processing algorithms for hearing aids. This paper presents a study
of the degradation of auditory nerve (AN) responses at a ...

Multi-resolution sub-band cepstral features strive to exploit
discriminative cues in localised regions of the spectral domain
by supplementing the full bandwith cepstral features with subband
cepstral features derived ...

Discharge patterns produced by fibres from normal and impaired auditory nerves in response to speech and other complex sounds can be discriminated subjectively through visual inspection. Similarly, responses from auditory ...

The effects are explored of using different dynamic features in
conjunction with an HMM that permits a dependency on both
preceeding and succeeding frames. In particular, features which
capture dynamic information are ...

A model of human speech quality perception has been developed
to provide an objective measure for predicting subjective quality
assessments. The Virtual Speech Quality Objective Listener
(ViSQOL) model is a signal based ...
